The black tank flush is a useful feature that helps you maintain your RV’s black tank. Whether you're prepping for storage, maintaining accurate tank sensor readings, or simply keeping your tank clean, using the black tank flush can make a big difference in the longevity and functionality of your system.

When Should You Use the Black Tank Flush?

You might consider using the black tank flush in the following situations:

  • Tank sensors are reading inaccurately: If your monitor panel shows incorrect readings, residue buildup could be to blame.

  • Before winter storage: Flushing the tank before storing your RV can prevent unpleasant odors and buildup.

  • Regular maintenance: Periodic flushing helps reduce the buildup of gunk and keeps the tank in good working condition.

How to Use the Black Tank Flush

Follow these steps to safely and effectively use the black tank flush:

  1. Hook up your sewer hose
    Always ensure your sewer hose is properly connected to a dump station or appropriate waste outlet.

  2. Locate the black tank flush inlet
    This is usually labeled and located on the exterior of your RV.

  3. Connect a garden hose
    Attach one end of a garden hose to the black tank flush inlet.

  4. Connect the other end to a water source
    Use a hose that is separate from your drinking water hose, and always connect through an inline pressure regulator to avoid over-pressurizing the system.

  5. Monitor tank levels
    It’s important not to overfill the tank. You can monitor your tank levels in one of two ways:

    • Use your tank monitor panel to keep an eye on the black tank fill level.

    • Open the toilet valve and visually inspect the tank level.

  6. Stop the flush when nearly full
    Once the tank is nearly full, shut off the water and disconnect the hose.

  7. Empty the black tank
    Drain the contents of the black tank into the sewer connection.
